When it comes to birthdays, no one knows how to party like Percy! Just follow his simple rules—like #2 "Happy times call for happy measures" and #9 "Be careful what you wish for"—to make the most of your celebration.

Through clever rhymes and bright, humorous illustrations from the creators of Thanksgiving Rules and Back-to-School Rules, Percy shows how to make the most of a birthday celebration.

Plastic bags are cheap and easy to use. But what happens when a bag breaks or is no longer needed? In Njau, Gambia, people simply dropped the bags and went on their way. One plastic bag became two. Then ten. Then a hundred.

The bags accumulated in ugly heaps alongside roads. Water pooled in them, bringing mosquitoes and disease. Some bags were burned, leaving behind a terrible smell. Some were buried, but they strangled gardens. They killed livestock that tried to eat them. Something had to change.

Isatou Ceesay was that change. She found a way to recycle the bags and transform her community. This inspirational true story shows how one person's actions really can make a difference in our world.
